Teleport is software which provides an SSH Jump Host (or Bastion host) service in a secure, modern, way, with support for role-based access control, and single sign-on.
It is a replacement for the ecAccess SSH service, and is operated by the CD Apps team and User Services.
This service is under development. Please continue to use the existing ECAccess service! |
The Teleport service provides:
The single sign-on step is performed using an application called "tsh
", every eight hours.
After that you use standard ssh or scp to connect to systems inside ECMWF.
tsh
The tsh
application is required to perform user authentication once every eight hours.
tsh
is open source, very portable, and has minimal dependencies.
$PATH
The binary is available for Linux 32-bit, 64-bit, and ARM, as well as signed packages for MacOS and Windows 64-bit.
MacOS users can also use homebrew for installation (brew install teleport
).
Once every eight hours, you will need to refresh your tokens by logging in to the ECMWF website.
Run tsh
, giving the location of our gateway:
tsh login --proxy=shell.ecmwf.int |
Your default web browser will open and you should login with your email address, workstation password, and then HID Token code.
tsh login |
If you're already logged in to the ECMWF website, or have recently logged in to this service, the password prompt might be skipped. |
OpenSSH 7.3 or later has a simple command line option to connect via our gateway (shell.ecmwf.int
) to the destination-host
:
ssh -J username@shell.ecmwf.int username@destination-host |
For example, if your username is ab0
and you wish to connect to ecgate
:
ssh -J ab0@shell.ecmwf.int ab0@ecgate |
The OpenSSH configuration setting for this is named ProxyJump
.
Destination hosts available through the Teleport gateway are:
For OpenSSH clients older than 7.3, the following will work in your ~/.ssh/config
file:
Host ecgate Username ab0 ProxyCommand /usr/bin/ssh -q -W %h:%p shell.ecmwf.int |
With the initial configuration you may be prompted for a password at the destination-host
.
For login without a password, add the Teleport certificate authority to your ~/.ssh/authorized_keys
file:
curl -fs https://nexus.ecmwf.int/repository/internal-teleport-configs/prod/teleport_user_ca.pub >> ~/.ssh/authorized_keys |
This configuration will allow access to any host which mounts the same |
scp and port forwarding will all work through the Teleport gateway.
X11 forwarding will work in a couple of months when we have an update from the vendor. |
